COSRX Vitamin C 23 Serum is generally best suited for normal, oily, combination, and dull skin types, particularly those concerned with hyperpigmentation, uneven tone, or early signs of aging. Its high concentration of 23% pure vitamin C (ascorbic acid) delivers brightening effects, evens out skin tone, and helps fight free radical damage. It also contains ingredients like hyaluronic acid and panthenol, which add hydration and soothe the skin, making it tolerable for many users. However, this serum may not be suitable for sensitive or compromised skin, especially those prone to irritation, redness, or conditions like rosacea or eczema. Due to its high potency, it can cause tingling, stinging, or irritation, particularly if your skin barrier is weakened or if you're new to vitamin C.
